Abstract
The present disclosure discloses a display driving apparatus in which the consumption power of a chip is optimized through control for each output channel of the chip. The display driving apparatus includes a consumption current control circuit for each output channel. The consumption current control circuit is configured to selectively provide a control current having a high current amount in order to drive an output voltage for the output side of an output buffer in response to a change in the pattern having a great difference between an input voltage and an output voltage.
